Finding out whether 32 or 64 bit version is installed

[whugemann]

I have asked this before in some other thread and didn't get an answer:
Is there any way to find out whether the IM version installed on an 64 bit system is 32 or 64 bit?

I often get asked about IM problems by colleagues from other cities, working with Windows batch files I wrote. It would help the diagnosis if I could get as much information as possible. A simple call with the -version option does however give no information on this, and the -verbose option does not seem to be available for -version.

I don't know how to do it on Windows, but on Linux you could look at
the output of "ldd" to see if it gives you a hint:

• glenn.rp> ldd /home/glennrp/im/q16/bin/q16convert
  [snip]
  /lib64/ld-linux-x86-64.so.2 (0x00007fb3c3f2f000)
  glenn.rp>
  
  [glennrp@studio ~]$ ldd /usr/local/bin/convert
  [snip]
  /lib/ld-linux.so.2 (0x0091c000)
  [glennrp@studio ~]$
  
  [glennrp@magick ~] ldd /usr/local/bin/convert
  [snip]
  libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003897200000)
  [glennnrp@magick ~]

I don't know how reliable this method is, but it seems that
glenn.rp and magick have 64-bit builds and studio doesn't.
